GUILFORD ROWELL, OF APPLETON, WISCONSIN, ASSIGNOR TO THE APPLETONMANUFACTURING COMPANY, OF SAME PLACE.

IM PROVEM ENT I-N GATE-ROLLS.

Specification forming part of Letters Patent No. 2 12,574. datedFebruary 25, 1879; application filed J annary 3, 1879.

To all whom it may concern:

Be it known that I,GU1LFORD D. HOWELL, of Appleton, in the county ofOutagamie and State of Wisconsin, have invented certain new and usefulImprovements in Gate-Rolls 5 and l do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in rollers for gates; and itconsists in making the head of the bolt on which the roller turns flaton two of its opposite sides, and forminga stud or projection on thesides thus flattened, for the purpose of holding two movable pieces inposition, which pieces enable the roller to swing around sidewise, aswill be more fully described hereinafter.

Figure l represents a vertical section of my invention. Fig. 2 is aperspective of the bolt and the two movable pieces that are appliedthereto.

a represents a comm on roller, upon which the gate moves back and forth,and which serves as a pivot for the gate to open and close upon. Thisroller is placed upon the end of the bolt c, which is screwed or driveninto the gatepost, and which has its outer end iiattened on two of itsopposite sides, as shown. Projecting outward from the center of each ofthese flattened sides is a stud or pivot, d, which catches in a recesson the inner iattened side of the pieces e. These pieces are oval ontheir outer sides at their largest end, have a shoulder, g, runningtransversely across them, and their inner or smaller ends rounded away,as shown.

Through the center of the roller is made an openin g large enough topass freely over the head of the bolt, but the rear edge of which opening forms a flange, t', to catch behind the shoulders g on the pieces e,so as to prevent the roller from moving too far forward. y The hub h ofthe roller projects forward beyond the front end of the bolt o, and hasa cap, l1 inserted in it, which is held in position by the pin a. Thiscap bears against the outer end of the bolt and prevents the roller frommoving backward on the bolt. The bolt projects a considerable distanceout from the post, so that the roller can be passed back over the headof the bolt before the pieces e are placed in position. After the pieceshave been placed upon their pivots, the roller is moved forward untilthe ian ge catches behind the shoulders on the pieces, when the cap isplaced in position and locked by the pin a.

The roller can turn freely around upon the end of the bolt withoutcoming in contact with anything else than the outer sides of the piecese, and as these pieces turn freely around upon their pivots the rollerswings freely around upon them. Where the journal is thus constructedthe roller turns around as the gate is being moved back and forth, andwhen it is desired to swing the gate open or shut the roller turnsfreely with it.

I am aware that ball-and-socket joints have been formed between the rolland the end of its supporting-bolt, and this I disclaim.

Having thus described my invention, I claim- 1. The gate-roller hereindescribed, consisting, essentially, of a fixed bolt, c, having itsattened ends provided with the pivots d, pivoted bearings e, thegate-roller a, and a suitable means, la, for holding the parts together,constructed substantially as shown.

2. In a gate-roller having a fixedbolt, e, provided with pivots d, oneor more detachable pieces, e, held to the roller, and a suitable holdingdevice, wherebyT the parts may be readily attached and detached,substantially as shown.

In testimony that I claim the foregoing I have hereunto -set my hand.

G. D. HOWELL.
